| | | removing element from document | removing element from document 2007-12-06 - By John Cartwright
Back
Sorry to reply to myself, but the following XPath approach seems to
work - is the the recommended solution?
-- john
List nodesToDelete = XPath.selectNodes(root, "//FIELD[@(protected)='#SHAPE#']");
int size = nodesToDelete.size();
for (int i=0; i<size; i++){
((Element)nodesToDelete.get(i)).detach();
}
